A;complteunderstanding@the mienten new? hei'ebtairid from, thefollowing., detailed, ,derden-L "i tion of' a reelforming affs'pecicembodiment thereof, when read in l'conjunction Withthe ape.pendeddrawingin which: Fig.l 1 isa fragmentary section of a reelfemr-I Abodyingthe invention rmounted on a sh'a'ft and Fig., 2V 'is afragmentary, partially sectional view ofthe reel andthe shaft.

Referringl now in ydetail to the drawing,V there is shown a split vreelIII` including a reel sectionl il, winch is provided with a reel head I2and a drum portionI lyhaving a tapered periphery `IlI.

Thedrum portion I3ris provided with a loolrev I5. which is designedtolreceive a shaft 20. of agear reducer 2l, driven` by a suitable motor`(not shown)A anddesigned to rotate the reel.` Set` screws 22` and 23,threaded into tapped bores 2.4', andw25, respectively, formed in thereellsection` I I serve to, prevent longitudinal movement of the"v reelsection Iljwith respect to the shaft `20A lock screws. 25 and 27 lool:Vthe set screws` 22 and 23,'` respectively, in place. A key 30 positionedfina slot3I formed in the reel section II andl a` slot. 32 formed intnevshaft 2,0 prevents relative rota' tion between the reel sectionIIand the shaft. The drum portion I3 of the reel section II providedWitha cylindrical projection 33, anda reelsection 36 having a drumportion 34 provided Witha cylindrical opening His designed to slide overthe. cylindrical projection 33; The cylinf' drical projection 33 fitssnugly within' the cylindrical vopening 35 formed in the reelsectionZilli. The drum portion 34 is provided with a relieved portion40, and the end of this drum portionts tightly against shoulder 4Iformed at the, end of the' cylindrical projection 33. The drum .por-

` tion 311 also is provided with a tapered periphery 42, which Vtapersoppositely from the ytaperedv periphery It of the drum portion I3 sothat thel peripheries of the drum portions I3 and 311v co operate toform a concave drum. The, reel section 'also is provided with a reelhead y133.

Theddrumrportion I3 of the reel sectionV I I is provided `with anenlarged passage 44 inmcommunication With the bore I5 and a tapped bore45 which is axially aligned With the bore I5. A

f locking bolt having a knurled head I5I extends through a hole 53'formed in the drum portion 34- of-the reel section '5t and is designedto be threaded into the tapped bore t5. The boltI 511` alsov has anannular collar 52 formed thereon which is'lsecured in an annular groove55 formedby the end of the reel section 36 and an annular. cap vISD,Welded thereto. A boss portion 54 of the -drum portion `I3 is designedto enter ithe opennag; termed in tlfledrurn.` iwrtioxi` ,34g .'Iliejknurled head 5I is provided with sockets 56-56 in which a pin (notshown) may be inserted to act as a lever arm for turning the head andthereby the bolt 50.

A jack bolt ElY may be screwed by a suitable wrench (not shown) into atapped bore 62 formed in the bolt 50. The tapped bore 62 is aligned withthe shaft 21El=andthe bolt 6'1 may be threaded into the tapped bore 52so that the right end of the jack bolt, as viewed in Fig. 2, may bepressed against the end of the shaft 20 to draw the reel I from theshaft 20 after the lock screws 28 and 2'! and the set screws 22 and 23have 1been loosened and the reel sections "II and 36 h'ave been lockedtogether .by the locking bolt U.

In the operation of the reel l0, the shaftrZU turns the sectional reelsecured thereto in fa `cloclcwise direction as viewed from the left endof the reel, as viewed in the drawing. As the reel is rotated, wire iswound ron the tapered periphiies SI"4 'and 42 of the 4drum portions I3and 34, respectively. ills the reel is so rotated, the threads of thetapped bore 45 and thebolt 50, being left hand threads, tend to threadthe locking bolt 5i) farther 'through the bore 'E5 so that the drumportion '34 is heid tignhy against the shoulder 4I of the drum portioni3, and the locking bolt 5ft may 'not te accidentali-y unsorewed frommetapped bore '55 during 'the take-up operation.

@After the wire has been wound into a coil, the motor 21 is stopped andthe locking bolt 5t is iinscrewed from th'etapped bore 45. As ythelocking ibolt 5B is unscrewed 'the collar 52 presses 'aginst the vcap 50and slides the reel section 36 to thele'ft, as viewed in the drawing,relative to the reel section il., the 'taperedfperiphery i2 of 'the'drum section 34 'permitting the drum portion y34 to be 'easily 'slidfrom under the coil of wire on the vreel l0. The reel section 3S lis-removed 'completely from the reel section Il and the "coil of Wire isslid off of the reel sectionlll, the tapered periphery M of the 'drumportion f3 'facilitating lthe removal of the coil of wire.

`rlie reel section 3S then Vmay be slid partially over the projection'33 of the reel Vsection i l and 1.

the rocking boit 'to 'may be tightened 'to slide the dru'rn "portion "34completely over 4the cylindrical projection 'and "to 'lock the reelsection '33 to lthe reel section I rl'he operation described hereinabove then vmay be repeated. The locking bolt 5U may `b`e tightened orloosened Vin the tapped `o re E5 by 'insertingagpin (not shown) into oneof 'the sockets '5B-5E lformed in the knurled head 51 of 'the flockinglbolt. After the reel section 3B has been looked in its .proper.position relative r to the reel section il, another coil of wire may beformed on the reel as described hereinabove. y HIf it is desired to"remove Athe reel from `the shaft-20, `thescrews`22,`23, '25 and 25 areloosened and the jack bolt 6'! vvis threaded into the bore 62 formed inthe locking bolt 5U to force the end of the wvjack bolt against the endof the shaft'20. A`s`t'he 4jack lbolt 'is turned further, relative tothe bolt 59, v'the reel Vsection i3 is pulled to Ythe left, a's viewedin Fig. l, relative -to the shaft, and is slid 'off of the shaft. The'force exerted bythe jack bolt AH the shaft is directed axially L0f theshaft so that the shaft is 4not -bent as @the reel is disengagedtherefrom. Thus, 'the reel section II m'a'y b'e tte'd tightlyupon theshaft and may be frenoved therefrom 'without damage to 'the straft. y d

The above-described reel i'nay be rapidly asseinlz/Ied'nddisasseibledand vcry'simple and eeiierriitafl in opration sind construction, lt

may be fitted tightly upon a shaft such as the shaft 20 and may beeasily removed therefrom without damage to the shaft. Also, the taperedperipheries I4 and 42 of the drum portions i3 and 34, respectively,facilitate the separation of the reel section 36 from the reel section Il when the reel sections have a coil of wire positioned thereon, andpermit the coil of wire to be easily removed from the reel sections.
